Abstract

A general framework is presented for optimal design based on multiple design
criteria which is suitable for performance-based design of structural systems operating
under uncertain risk. Reliability-based design criteria are used to maintain
specified levels of structural safety by properly taking into account the uncertainties
in the future seismic loads. The ground motion uncertainty is characterized
by a probabilistic response spectrum developed from available attenuation formulas
and seismic hazard models. A simple illustrative example is given.
